摘　　要：为了明确柴达木盆地雅丹地貌发育的风况特征,对盆地中南部鲸背状雅丹区和西北部长垄状雅丹区的风况分别进行了长期的野外实地观测。对实测的风速风向数据按照罗盘16方位分风速段统计分析,计算输沙势,得到柴达木盆地雅丹地貌区风况数据集。该数据集包括两个数据文件:(1)盆地中南部的鲸背状雅丹区风况数据(WinReg_haleBackYardang_B);(2)盆地西北部的长垄状雅丹区风况数据(WinReg_ongRidgeYardang_B)。每个数据文件均包含3个工作表,分别为观测周期内的原始风速风向记录,各月份、季节、年度的风频和输沙势。本数据集存储为.xls格式,压缩后的数据量为2.73 MB。本数据集不仅可准确阐释柴达木盆地雅丹地貌发育的风况特征,也为进一步研究雅丹地貌的发育演化模式奠定了基础。本数据集的相关研究成果发表在《中国沙漠》2013年33卷第5期和《Journal of Arid Land》2019年11卷第5期。In order to demonstrate the wind regime of yardangs,long term field observations had been carried out to the whale back and long ridge yardang fields in the south-central and northwestern part of Qaidam Basin,respectively.Wind frequency was counted according to the 16 points of compass and corresponding wind speed classes,and the drift potential was calculated according to the method proposed by Fryberger et al.This dataset includes two group files:(1)the wind regime data of whale-back yardang field in the south-central Qaidam Basin(WinReg_WhaleBackYardang_QB);(2)the wind regime data of long-ridge yardang field in the northwestern Qaidam Basin(WinReg_LongRidgeYardang_QB).Each data file contains three worksheets,namely,the original record of wind speed and direction in the observation period,wind frequency and drift potential of each month,season and year.The dataset was archived in.xls data format with the data size of 2.73 MB(in.rar file).This dataset can not only demonstrate the wind energy environment,but also beneficial to propose the development and evolution model of yardangs in the Qaidam Basin.
